# Does HUE Free Gift Upsell work with Sticky Cart or Slide Cart Drawer apps?

> ❌ Currently not supported

### Slide Cart / Cart Drawer apps
Most slide cart or cart drawer apps fully control the cart experience.
Because of this limitation, HUE Free Gift Upsell may not be able to:
* Show discount widgets properly
* Apply discounts inside the cart drawer
* Display offers correctly within third-party side carts
###### Common issue:
* Discount not showing in slide cart
* Offer widget not appearing inside cart drawer

Sticky cart apps usually take control of:
* Add to cart buttons
* Checkout buttons
This may prevent HUE Free Gift Upsell from properly triggering campaigns or applying discounts during checkout.
